When 0 is written after reading ADF = 1
A/D Interrupt Enable
Enables ADI interrupt by ADF when this bit is set to 1.
A/D Start
When this bit is cleared to 0, A/D conversion stops and
enters wait state. When this bit is set to 1 by a conversion
start trigger from software, TPU, or TMR, A/D conversion
starts. This bit remains set to 1 during A/D conversion. In
single mode, this bit is automatically cleared to 0 when
conversion on the specified channel ends. In scan mode,
conversion continues sequentially on the specified
channels until this bit is cleared to 0 by a reset, or
software.
Reserved
This bit is always read as 0 and cannot be modified.
When A/D conversion ends in single mode
When A/D conversion ends on all channels specified
